Clemente Aguirre sentenced to death in 2006 after murdering 2 women

The woman defense attorneys claim killed her mother and grandmother in 2004 took the stand Wednesday at a hearing designed to free a man sitting on death row for the crime.

Samantha Williams answered questions about her mental health issues that date back to the time she was 14 years old.

Her mother, Cheryl A. Williams, 47, and her wheelchair bound grandmother, Carol Bareis, 68, were both found stabbed to death at their Altamonte Springs home. Williams had been stabbed 129 times. Found with blood soaked clothing in a bag, their next door neighbor, Clemente Aguirre, was tried and sentenced to death for the murders, even though his blood wasn't found at the crime scene.

New DNA evidence shows Samantha Williams' blood was found at the scene.

"It could have been from me slapping a mosquito on the wall," Williams said in testimony. "It could have been from my putting my hands through a window and touching the wall afterward."

Williams referred to her mental health problems and violent temper several times throughout her testimony, including details about a fight she had with her now-deceased mother the night before she died.

"The fight was because ice was dropped on the floor, and my mom said you wouldn't do that at your house. I said, 'I don't have to put up with this. I'm out.'"

She told the court she didn't remember telling police that demons were in her head and that they told her to kill he mother and grandmother after she set herself on fire two years ago.
